With reference to the instinctiTe endowmentB of tins 

 kind in kittens, I may also qiiote die kXkmJag, wUdi I find 

 amon^ ^Ir. Darwin's iiSS : — 



"the many cases of inborn liear or ferocitj in joung 

 animals direeted towards porticidar objeets, as wdl as tlie 

 loss of these indiTidiialized paaaoos, seems to me extreme^' 

 corions. Let anj one who doubts their erjatenfle gire a 

 mouse to a kitten taken eazlj from its mother, and wfaieh has 

 never befose seen one, acd obserre how soon the kittea

The only odier ebaenaliflns made by Mr: Spalding which 

 It is desiral^ to quote are those bf wfaidi he proied expm- 

 mentally that yooi^ birds do not require; as was otdimnihr 

 supposed, to be taught to ftj, but fly instinetivi^. This fact 

 was proved by keefing yoon^ swaDows csged m^diey were
